I'm running Debian on an old Dell Vostro 1520 - old and slow, but has
been working fine. Recently the PSU has stopped charging. It is
genuinely empty; if I power down and then try to boot with no power
cable attached the laptop is completely dead.
I guess it's most likely this is a hardware failure, but since I'm
unlikely to find a viable replacement for the battery I'm hoping there
might be some firmware or other software change that could account for it.

Is any of that helpful for working out what might be wrong?
Thanks for any advice
